Orange County,
1845

(Formerly
Mosquito County)

Orange
County (then called Mosquito County)as shown on Sidney E. Morse's 1845
A System of Geography for the Use of Schools. Of interest, this
map is the first school atlas to make use of the cerographic process,
also created by Morse. This process allowed an original of the map to
be drawn as a positive, unlike earlier ways of creating maps, which required
the original to be a negative image of the map. It had significant impact
on mapmaking and became a widely used process.
